* This makes assignStereochemistry cleanIt=True not remove CIS/TRANS
bond stereo chemistry that was manually added as described in issue #1614.
Incorrect CIS/TRANS stereochemistry will still be removed by
'cleanIt=true' if symmetry is detected. However, this symmetry
detection doesn't work in more complex pseudo-stereo chemistry cases:
bond stereo that depends on other bond stereo to break symmetry; and
bond stereo that depends on other atom stereo centers to break
symmetry. Test cases for these cases have been added ifdef'd in based
on USE_NEW_STEREOCHEMISTRY.
However, getting USE_NEW_STEREOCHEMISTRY to work in a copacetic way is
not trivial, I tried a little bit here to no avail. I'm leaving the
test cases checked in as they should be useful when we decide to make
the plunge into using Canon::chiralRankMolAtoms for symmetry detection
instead of the CIP ranks.
So this fixes at least the glaring issue of STEREOCIS and STEREOTRANS
being incorrectly removed by 'cleanIt=true' when it is indeed valid
stereo. The checks made for symmetry are rudimentary, but don't feel
complete.
* add another test; make what's being tested explicit
* test smiles generation and function when Hs have been added
* add a test that fails
* I think that it's ok to remove this
* backup
* At this point all tests pass.
Bond wedging is now handled even if sanitization is turned off when mol files are read
* adjust to code changes
* fix a couple problems caused by rebase
* update docs
* Add parameter to skip proximity bonding during PDB reading
* Test proximityBonding flag
* Remove multivalent Hs and bonds to metals in PDB
* Add tests for multivalent Hs and metal unbinding
* Remove covalent bonds to waters
* Test unbinding of HOHs
* Refactor funxtions
* Rename flag for cosistency
* Include flavor in double bond perception
* Add metalorganic test (APW ligand)
* Validate input foe IsBlacklistedPair and minor changes.
* Add support for dative bonds to molfile reader plus writer and to SMILES reader (SMILES writer already supports it).
Initial V3000 molfile reader and writer dative bond support by Esben Jannik Bjerrum.
* first pass at adding -> as dative bond in smiles/smarts
more testing required
* all tests pass
* update .cmake files for lex
* patch from Roger Sayle to support nucleic acids as well as amino acids
* add some tests which do not yet pass
* fix a bug I introduced in residue name parsing
* basic sequence testing
* add some more tests
a blank line in a property when strictParsing = false; properties
are truncated after the first blank line. Also spurious lines
before the first property are tolerated (and ignored)
- added the strictParsing parameter to the setData() method in C++
and to the SetData method in Python. Previously, when the setData()
method was invoked, the strictParsing flag could not be set.
Moreover, df_strictParsing was not initialised , which might result
in undefined behaviour
- added relevant C++ and Python tests
